Vehicle body lower structure

Abstract

The disclosure provides a vehicle body lower structure, which may improve aerodynamic performance and inhibit the airflow guiding plate from being over-expanded or detached. The vehicle body lower structure includes an airflow guiding plate that is arranged on the vehicle body of a vehicle and is movable between a receiving position covering the lower part of the vehicle body and a deploying position protruding downward. The vehicle body lower structure further includes: a hook member, which is provided on the upper surface of the airflow guiding plate. When the airflow guiding plate is in the deploying position, the hook member is locked onto the buckle part of the vehicle body. When the airflow guiding plate is located at the receiving position, the hook member is separated from the buckle part of the vehicle body.

What is claimed is: 
     
       1. A vehicle body lower structure, comprising an airflow guiding plate that is arranged on a vehicle body of a vehicle and is movable between a receiving position covering a lower part of the vehicle body and a deploying position protruding downward, wherein the vehicle body lower structure further comprises:
 a hook member, which is provided on an upper surface of the airflow guiding plate, wherein 
 when the airflow guiding plate is located at the receiving position, the hook member is separated from a buckle part of the vehicle body, and when the airflow guiding plate is in the deploying position, the hook member is locked onto the buckle part of the vehicle body, 
 the buckle part is a part of a front frame of the vehicle body, and the buckle part is formed by a crossbar extending in a left-right direction of the vehicle. 
 
     
     
       2. The vehicle body lower structure according to  claim 1 , wherein
 a front end of the airflow guiding plate is rotatably connected to the vehicle body through a shaft member extending in a left-right direction of the vehicle, and 
 the hook member is fixed to the buckle part at a position further rearward than the shaft member. 
 
     
     
       3. The vehicle body lower structure according to  claim 2 , wherein
 the hook member has a claw part protruding toward the rear of the vehicle, and 
 the claw part is located at a position higher than the buckle part. 
 
     
     
       4. The vehicle body lower structure according to  claim 1 , wherein the front frame is disposed at a lower part of a front of the vehicle, and the front frame is disposed adjacent to a pair of left and right front wheels. 
     
     
       5. The vehicle body lower structure according to  claim 1 , wherein the front frame includes a pair of side frames extending in a front-rear direction of the vehicle, and the crossbar connects the pair of side frames. 
     
     
       6. The vehicle body lower structure according to  claim 5 , wherein the front frame includes:
 a first bulge part extending from one of the pair of side frames to an outside in the left-right direction of the vehicle; and 
 a second bulge part extending from another of the pair of side frames to the outside in the left-right direction of the vehicle, 
 wherein in the front-rear direction of the vehicle, the crossbar overlaps with the first bulge part and the second bulge part.
